AIR CONDITIONER

PURPOSE: To reduce the loss of driving power of a four-way valve, and to simplify and miniaturize a DC power source. CONSTITUTION: This air conditioner comprises the four-way valve 18, a first DC power source 14, a first switch 19 for applying the first DC power source to a four-way valve coil, a se...

Zusammenfassung:	PURPOSE: To reduce the loss of driving power of a four-way valve, and to simplify and miniaturize a DC power source. CONSTITUTION: This air conditioner comprises the four-way valve 18, a first DC power source 14, a first switch 19 for applying the first DC power source to a four-way valve coil, a second DC power source 20, a second switch 21 for applying the second DC power source to the four-way valve coil, and a three-phase inverter 16 for driving a compressor 17, the first switch is turned on only for a predetermined time of several seconds, and then the second switch is continuously turned on to drive the four-way valve, whereby the air condition is provided with the driving sequence where an initial charging period of a boost lap power source 15a and the turning-off of the first switch are not simultaneously generated. 노이즈의 영향을 받기 어렵게 하고, 로터의 확실한 위치 검지를 실행할 수 있으며, 로터를 안정적으로 회전시킬 수 있게 한다. 전압귀환 콘덴서(21, 22)를 구비함으로써 히스테리시스 전압 변화를 급격하게 하고 또한 희망하는 변화량으로 한다.
